Both woodland and tundra forms typically travel to wintering range in mature conifer forests to feast on both arboreal and terrestrial lichens. In the summer they prefer lush swamp areas, in the fall they move through mushroom-growing forests further up to moorlands for the winter, eating lichen from under the snow. The indigenous people of Canada make frequent use of reindeer moss in their diet, though it’s as more of a filler than a primary food source. The photobionts themselves are similarly unrelated. If the total energy need of a reindeer foraging in thick snow is 25.0–28.0 MJ per day and if the proportion of lichen in reindeer nutrition is 70%, a reindeer has to acquire 1.9–2.1 kg DM of lichens per day in order to satisfy the total energy need. In the winter months, 90% of the reindeer's diet is constituted of lichens, specifically Cladonia rangiferina (r eindeer l ichen) . It's a particularly valuable fodder for the reindeer herds, and, historically was used by the Denaʼina of the south central Alaskan region as food, who prepared it as seen on the show. The only way that these lichen-forming fungi are connected is by their means of nutrition: the photobiont. Reindeer lichen cover was 1.3% in 140-year-old stands; reindeer lichen had been replaced successionally by Schreber's moss and knight's plume moss (Ptilium crista-castrensis) . In winter, reindeer prefer cladonia stellaris (reindeer moss) and cetraria nivalis, but if these are not available they eat other types of lichen, leaves and other plants with a lower nutritional value. Related Article: 10 Facts about Leaves. If they have access to nutrition from other plants, reindeer are by no means dependent on lichen. They are also subject to common deer diseases such as brucellosis, chronic wasting disease and West Nile virus.

During the winter months, reindeer feed largely on lichen, so rather than leaving the reindeer carrots this Christmas, maybe you could search for some lichen to leave out for them. It's not actually a "moss", but a lichen, Cladonia rangiferina, although similar varieties are often called "Reindeer Moss". The result was a concoction known as "stomach ice cream".
